I am 44 and have been through two bridges in my life my friend, and I hate to be the bearer of bad news but you are in for a long road of dental problems. Dentists like doing bridges because they are very profitable for them. They can charge alot of money per crown for a minimal amount of work and its very good for them. Unfortunately for the patient, it is a miracle if you get 10 years out of a bridge with no problems. They put a tremendous amount of stress on your roots leaving you with a removable denture as your only option when the bridge eventually fails. All you are doing with a bridge is trading one set of dental problems today for an even greater set of dental problems tomorrow. The teeth you have capped now will sooner or later need to be pulled entirely and replaced with a partial removable denture and there is simply no way around that fact.
Some dentists are better than others just like doctors, nurses, or anyone that provides a service. Did the same dentist do both of your bridges? Was it a PFM (porcelain fused to metal) or pure porcelain bridge? PFM bridges are stronger. Did you take care of your bridge by flossing under it every day and flossing around the real teeth on both ends of the bridge? How many teeth did you have bridged? If it were quite a few teeth then the bridge would put a lot of strain on the end teeth and there may have been better options. Other than that, there shouldn't have been a reason for you to have problems out of the capped end teeth. There are no sure things dealing with teeth, so telling me without a doubt my capped teeth will eventually need to be pulled may or may not be true. Telling someone your problems will eventually become their problems is just a blanket statement and flat out guess.
Yes, there are tradeoffs to bridges but depending on your own dental situation it may or may not be worth it to go with a removable partial. When I was 13, I had my front left tooth totally knocked out and I had a removable partial until I was 17 when my teeth had matured enough to be fit with a 3 unit bridge. I wouldn't trade the 17 years I had no problems and kept that annoying partial for anything in the world.
Dentists have to make profit to stay in business and the lab has to profit as well. My two partials were not cheap either. They are so annoying to deal with. You should take them out every night and have to soak them in denture solution. Then, even if you use denture adhesive and actually get it to stay well, you still can't bite into things as well. They often come loose and you have to reglue or go with it loose until the next day. Food gets impacted around it's edges, maybe up under it, and you have a piece of plastic you can constantly feel inside your mouth. I had a new partial made which I kept for six months this time around and couldn't wait to get a bridge. I HATE partials.
You're bad experience doesn't mean everyone will have a "long road of dental problems." To each his own and if you prefer partials that's fine. It seems like you are hell bent on pushing your thoughts on others. Anyone with missing teeth is going to have dental problems which will probably continue as more bone loss occurs, regardless of whether you have a bridge or partial.
You're wrong about bridges and partials being the only options. Implants are also an option. Very, very expensive but you normally get a bone graft if you've had any bone loss due to missing teeth and rods are implanted into the bone to which "teeth" can be attached. These often look less natural than bridges, though.
My insurance only pays half on bridges so if you feel the price is too high, take out supplemental insurance if possible.
It sounds like you either have an axe to grid with a dentist that did a poor job or feel like you were price gouged.
